IMPROVEMENT IN DU MPlNG-CARS.

Specification forming part of Letters Patent No. 178,070., dated May 30,1876; application filed January 3,, 1876.

i To all whom it may concern:

Be it known that I, DAVID MANUEL, of

so connected with the rockers as to allow them to. work freely, and atthe same time keep them on the rocker-bed; and it also consists of acontrivance of the brakes to swing together with the wheels.

Figure 1 is a plan of my improved dumping-car inverted, and a,horizontal section of one of the wheels and "a bearing. Fig. 2 is atransverse section. Fig. 3 is a side elevation 5 and Fig. 4 is ahorizontal section taken on the line a; a: of Fig. 3. Fig. 5 is asectional elevation to exhibit the connection of rockers and links.

Similar letters of reference indicate corresponding parts.

A represents the independent axles for each wheel B, said axles having aball-and-socket outer bearing 0, and being at the inner end lit-ted in abearing, D, swiveled to a rocking yoke, E, whereby the wheels are freeto turn to the curves of the rails in going around them, and swing backto the line of the car again as the rails assume straight lines, thusenabling the car to run much easier on short curves than when mounted inthe ordinary way. The car-body F is mounted on rockers G, for dumpingeasily, and the rockers are set on rocker-beds H, which have theirsupport on the perch I of the car-frame, and are connected to therockers by links J, which allow the rockers to work either way, and atthe same time hold them on the beds. The box brake-bars M are, inconsequence of the swingin g contrivance of the axles, pivoted to theirsupports N, so that they can swing the brakeshoes 0 in unison With thewheels, and the shoes have a rod, P, extending part way down the facesof the wheels by which the wheels are made to swing the brakes. Thebrakesupports are pivoted at R, and have each a short lever, S, both ofwhich project over the short arms T of the brake-lever U that both maybe worked by either of the brakelevers.

Having thus described in y invention, I claim as new and desire tosecure by Letters Patent- Y 1. In independent axles, having aball-andsoeket outer bearing, the central inner connectin g swivel-yoke,to serve as an inner bearing for the axles, as shown and described.

2. The rockers of the car-body, mounted on rocker-beds supported on theperch of the car, and connected to the rockers by links, in the mannerdescribed.

- DAVID MANUEL.
